مقدمة:

XNR Series Melt flow index Tester is used to determine the melt mass-flow (MFR) of thermo resin. The apparatus fits for the standards of GB 3682, ايزو 1133, أستم د 1238, أستم د 3364, من 53735, UNI-5640, JJB878.

مبدأ الاختبار:

Melt Flow Index Tester uses a high-temperature heating furnace to make the measured object into a molten state under the specified temperature condition. The test object in this molten state is subjected to an extrusion test through a small hole of a certain diameter under a prescribed load. In the production of plastics, the melt index is often used to indicate the fluidity, viscosity and other physical properties of polymer materials in the molten state. The so-called melt mass flow rate refers to the average weight of each segment of the extruded sample converted into 10 minutes of extrusion.

تطبيق:

Melt Flow Index Tester is mainly used for the melting index test of polyethylene, polystyrene, polypropylene, ABS resin, polyoxymethylene resin, polycarbonate, nylon, fluoroplastics and other high polymer plastics.
